TO ALL WHOM IT MAYCONCERN:

y Be it known that we, CHARLES R. BAeoNaud Grenen D. CLARK, both of the city of Newark, and State of New Jersey, have invented a new and useful Device for Holding Bleaching-Boxes; and we do declare thc following to be a full, clear, and exact description thereof, which will enable others skilled theart to make and use the same, reference being had to the accompanying plate of drawings as forming a part of this specification. f Y

Figure -I'is a perspective of our device.

The invention which is the subject of this applcationvconsists of a frame for holding the box, and adeviee' for securing the box to the frame. The frame is of iron or other suitable'material, in one piece, and consists of a handle, H, disk or 'ring R, lugs L L L, and legs P P .P VThe disk is a dat ring, whose diameters are respectively greater and less than the diameter of the box to be held, the breadth of the ring being sniic'ient to allow for the ordinary variation in the sizes of boxes, and to give place for lugs L L L, which project fron its upper surface, as will be presently explained. From the under surface of the ringfour legs projeet,lone at cach extremity 'of the diameter, which is parallel with the axis of the handle H, and oneV ati-each extremity of the axis, which is perpendicular to the former. The inner surfaces of two of the lugs which project upward from the upper surface of the ring are cut under from the inner top edge to the surface of the ring. Throughthe third luga thumb-screw, S, projects linward and radially in such a manner that it drivesthebox against the other lugs, theform of the lugs and-the position of the screw holding the box firmly upits scat. y

From the description given it must be evident that if a box be place-don the ring and against the innerA surfaces of the lugs, which are ,cut under, and the screw be turnedn such a direction as torpress the boxV against the lugs, the boxwill be firmly and securely held in place; whereas,l if the screw he'turned in the oppor site direction, the box will be released.

We have invented and applied a fastening-device, which differs from the Oncabove described. It consists of a clamp or' slide, C, and screw M. This clamp or slide rests on the upper surface of the ring to which itis@ secured in the desired position by the screw M, whose axis is perpendicular tothe plane of the upper surface of thering, through which it projects from above.- The clamp is a ilatpiece of metal, one end of which is bent nearly atv right angles tb its length. It is arranged'radiall'y with the ring, and with its bent end inward. A' slot is cut from this piece in the direction of its length, through which the screw above described is passed, a shoulder of the screw, when thescrew is turned down, drawing it tightly against the disl, as will be evident without further explanation. The thickness of this piece decreases from the angle to the outer end, so that the piece shall not work loose or be pressed or driven outward, and the box thereby loosened, when the slide has been placed against the box and the screw turned down. This form ofthe clamp'we regard as very important,

for the reason above stated.

The'construction can he applied to boxes of all sizes. 4 Having described our device for holding blacking-boxes, we claim, and desire to'secure by Letters Patent,

as follows, viz: i u i .im

We claim a holder for blaclring-boxes, consisting. of the frame R, lugs L, clamp or slide C, and screw M,

when constructed substantially as herein set forth.
